My parents make these fish tacos all the time and I am finally getting around to share the greatness that is Blackened Fish Tacos with all of you. Gotta love those good family recipes!

I wish I could share a taco with each of you to show all of you how amazing they are – but the technology isn’t there yet. I’m hoping scratch & sniff screens are in the near future!

These fish tacos are absolutely divine and I don’t say that lightly. I am always on the hunt for a good fish taco and try them at restaurants all the time…and these are better than 98% of them.

The method of cooking your fish in a cast iron skillet with a bunch of butter is brilliant and gives it that perfect texture and crispy outside. You want to find a good blackening seasoning. 

And the sauce on these, oh I could write a song about this fish taco sauce. It seriously has all my favorite flavors in it and I love that you get creamy and slightly spicy all in one yummy sauce. Oh and it has lime and cilantro in it. BEST EVER.
